713.25
Effect of adoption of plans.

The planning commission of any municipal corporation to which a
regional or county plan is certified under section
713.24 of the Revised Code, may
adopt such plan, and it shall thereupon have the same force within such
municipal corporation as is provided by law or charter for plans prepared and
adopted by the local planning commission. The board of county commissioners may
adopt such plan so far as it relates to nonmunicipal territory. Thereafter no
public building, roadway, bridge, viaduct, or other public improvement or
utility, publicly or privately owned, whose construction or location would
constitute a departure from the plan, shall be constructed or authorized by the
board except by unanimous vote. Such plans shall not designate the specific
lots or parcels of land upon which such system, facilities, buildings, and
improvements are proposed to be placed, but only the general site or location
thereof. The effect of the adoption of such plan by the board shall cease as
regards the location of any sewage or garbage disposal plant, and no official
action of the board shall be controlled thereby in such respect, unless the
site shown on the plan as the location of such plant is purchased within six
months after the adoption of the plan by the board, or unless proceedings for
the appropriation of the necessary property are commenced within a period of
six months and such property is then or thereafter appropriated in such
proceedings.
